What pinion gear should I use on the Tekno ET48 2.0?

It depends on your motor and the track. In the 1/8 4WD truck class, racers gear by final drive ratio: 1800–2300 Kv near 13.97. On the ET48 2.0's stock 44T spur that is about 14T for 1800–2300 Kv. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the ET48 2.0 selected.

What is the internal ratio (transmission ratio) of the Tekno ET48 2.0?

The ET48 2.0 has an internal ratio of 4.444:1. Final drive ratio = spur ÷ pinion × 4.444. With the stock 44T spur, a 12T pinion gives an FDR of 16.29 and a 18T gives 10.86.

How many teeth is the stock spur gear on the Tekno ET48 2.0?

44 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

What shock oil does the Tekno ET48 2.0 come with?

Out of the box the ET48 2.0 runs 700 cst front, 600 cst rear (Tekno oil), on 4x1.2mm + 4x1.3mm CNC (#6180) front, 4x1.2mm + 4x1.3mm CNC (#6180) rear pistons. That is the kit setup; you will need to adjust it for your track conditions. The RC Setup App can help dial it in.

What springs does the Tekno ET48 2.0 come with?

The kit springs are 5.60lb Yellow (#6092) front, 4.48lb Yellow (#6082) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.

What diff fluid does the Tekno ET48 2.0 come with?

The kit diff fluid is 20,000 cst front, 20,000 cst center, 10,000 cst rear. Thicker front adds steering on power; thicker center sends more drive rearward; thicker rear stabilizes the car under throttle.
